contrib/ofed/libibverbs/fixes/pthread_cond_t_fields.patch

   1 move  pthread_cond_t fields to the end of structs, because
   2 their size changed from RHAS4 to RHAS5. In all the cases,
   3 the intervening entries were not accessed outside libibverbs
   4 (in non-XRC applications).
   5
   6 The structs modified are: ibv_cq, ibv_srq, and ibv_qp.
